Mine is under the bed so it could be anywhere. It should be within a few feet of the batteries though. The solar panel is one of the few things that just does what it does with no interaction from the owner. You can look in the battery bay and make sure all the fuses and dc breakers are on. A few tests with a voltmeter on a sunny day without the coach running or being plugged in to shore power should tell you if it is working.
